私はクラス内の最終プロジェクトのためにソーシャルメディアのウェブサイトを作っています。このページでは、ユーザーが壁のポストに画像を挿入してイメージできるようにしようとしています。私は、ファイルを取り込むhtml形式のコードを持っています。それは、それが自分自身であるときには完全に動作しますが、私のコードに入れようとすると、PHPの$ _FILES配列は常に空です。私はすでにphp.iniファイルの最大ポストサイズと最大入力サイズが十分に大きいことを確認しましたが、この時点で何をすべきか分からず、stackoverflowの他のポストごとにすべての提案を試みました。このここに入力HTMLファイルの入力が機能していません
<form method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="myFile">
<input type="submit" value="Upload!" name="submitForm" />
</form>
のための私のフォームは、私は、フォームとPHPのコードはI場合は正常に動作、それを処理するために言ったように
if (isset($_POST['submitForm'])) {
print_r($_FILES);
}
フォームを処理するPHPコードですそれらを自分のファイルに入れてください。ファイルに入れたら、実際には使用したくはありません。ここにファイル全体があります。他のコードが壊れていると思われます。

質問には関係のないコードがたくさんあります。この問題を再現する最小限に抑えることができますか？ [MCVE]（http://stackoverflow.com/help/mcve）を参照してください –
フォームをあなたの 'PHP'ページに送りますか？ –
申し訳ありませんが、あなたはそれが何を意味するのか分かりません。あなたはフォームが処理するために別のPHPファイルにデータを送信するかどうか尋ねていますか？それがあなたが何を意味していたのであれば、フォームにはアクションやonsubmit機能はありません。 –
